In this work, an improved palmprint recognition system based on 3D ultrasound images is proposed and experimentally validated. The system exploits an ultrasound gel pad as coupling medium, which results much more practical and non-invasive in real applications than water. An ad hoc recognition procedure has been derived; it uses as input a 2D image of the palmprint at a fixed under skin depth and extracts main features exploing the Frost filter and a series of morphological operations. The recognition system has been preliminarily evaluated through verification experiments carried out on an ad hoc established database composed of 75 samples from 17 different volunteers.

Abstract

In this work, an improved palmprint recognition system based on 3D ultrasound images is proposed and experimentally validated. The system exploits an ultrasound gel pad as coupling medium, which results much more practical and non-invasive in real applications than water. An ad hoc recognition procedure has been derived; it uses as input a 2D image of the palmprint at a fixed under skin depth and extracts main features exploing the Frost filter and a series of morphological operations. The recognition system has been preliminarily evaluated through verification experiments carried out on an ad hoc established database composed of 75 samples from 17 different volunteers.
